Issue in using a Julia script

I have installed Atom 1.53.0 on my Linux machine and then I’ve installed Juno in order to run Julia.
I must use a cloned GitHub repository as a Julia package, so I go to the directory where I cloned that repo, I start Julia and then I do “using” the package. So far so good.
Now, I need to write a Julia script and then execute the code and that’s the problem: after opening a new Julia file (through Juno) within this same cloned directory, the code I write in that new file is not executed inside the pane where Julia is activated. In other words, script e Julia pane are detached.
How can I create a Julia script in order to run the code into the Julia pane activated inside a specific folder?
Thank you very much in advance and best regards
